Item 8.01 Other Events.

Date of Annual Meeting of Stockholders

As previously announced in the Current Report on Form 8-K dated September 28, 2026, the board of directors of RingCentral, Inc. (the “Company”) had scheduled the Company’s Annual Meeting of Stockholders (the “2026 Annual Meeting”) for November 2, 2026. The board of directors has since rescheduled the 2026 Annual Meeting for December 7, 2026, commencing at 9:00 a.m., Pacific time. Because the new date of the 2026 Annual Meeting is not more than 25 days before the one-year anniversary of the date of the Company’s 2025 annual meeting of stockholders (which was held on December 31, 2025), the deadlines for any stockholder nomination or proposal outside of Rule 14a-8 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), have reverted to the deadlines originally disclosed in the Company’s proxy statement for its 2025 annual meeting of stockholders, as described below.

As previously announced, proposals to be considered for inclusion in the Company’s proxy statement for the 2026 Annual Meeting made pursuant to Rule 14a-8 under the Exchange Act must be received by the Company at its principal executive offices before 11:59 p.m., Pacific time, on October 9, 2026, and this deadline is not changing as a result of the rescheduling of the 2026 Annual Meeting. In order for a stockholder proposal made outside of Rule 14a-8 under the Exchange Act or the nomination of a candidate for director to be considered “timely” within the meaning of Rule 14a-4(c) under the Exchange Act in respect of the 2026 Annual Meeting, such proposal or nomination must be received by the Company at its principal executive offices not earlier than the close of business (5:00 p.m., Pacific time) on September 25, 2026 and not later than the close of business (5:00 p.m., Pacific time) on October 25, 2026, and be in compliance with the Company’s bylaws and, if applicable, Rule 14a-19 under the Exchange Act.

All proposals and nominations should be sent to the Company’s Secretary at the Company’s principal executive office: RingCentral, Inc., Attention: Corporate Secretary, 20 Davis Drive, Belmont, California 94002, or by email to: [email protected].
